Agricultural use is the main way of recycling sewage sludge. Besides providing nutrients and organic matter to crops and soils, it is an important alternative for recycling this residue. However, problems during the sewage treatment process may generate sludge batches with an acidic pH. Thus, it is essential to understand the consequences of using such sludge on soils and plants, and to explore ways to overcome this limitation. The objective of this study was to evaluate addition rates of anaerobic sewage sludge (ASS) with acidic compositions on the soil fertility and performance of lettuce plants. Additionally, a methodology for pH correction of ASS with acidic pH is proposed. An agronomic experiment was conducted in a greenhouse using seven addition rates of ASS (0.0, 0.25, 0.5, 1, 2, 4 and 8 g kg−1 in dry basis), treated with an additional step of disinfection (solarization), and applied in an Albaqualf soil cultivated with lettuce (Lactuca sativa). Soil and leaf chemical composition, as well as chlorophyll index and the dry matter of lettuce leaves were evaluated. Failures during the acidogenesis phase of the anaerobic digestion process were probably the cause of ASS acidification. Although this ASS increased soil fertility indicators and plant dry matter, it significantly reduced soil pH, thereby requiring a complementary assay to correct its pH up to 6.0, which was achieved through liming. Anaerobic sewage sludges with an acidic pH can be effectively used in agriculture after being dried and disinfected through solarization, followed by pH correction, avoiding negative impacts on soil chemical attributes and plant response.

Integrated management approaches are essential for the sustainability of the beef cattle production system in the Pantanal wetland, and it would direct the adoption of adequate management practices that favor multiple ecosystem services and biodiversity. This paper exempli?es the evaluation of the pasture attributes in a ranch at the Nhecolandia sub-region, Pantanal. The evaluation is based on an indicator of natural pasture conservation status (PCS) applied to landscapes with dominance of native grasslands. To estimate the net primary productivity (NPP) and forage provision, the vegetation at two different landscapes was mapped, one with "regular" and another with a "good" PCS performance. Grassland landscape with "good" PCS presented more than three times NPP than the "regular" one, reflecting the greater forage provision and grazing capacity. This result indicates the PCS indicator is suitable to differentiate among grassland condition with potential positive impact on animal performance and ecosystem services. The integration of different complementary evaluation tools provides useful information for decision making on sustainable grassland management. |
